So my truck keeps puttering out on me . I don't think it's my fuel pump case it still starts. But it will send me all the way down to 30 40 mph . Or just just die sometimes.. and sometimes it won't start.. it pops as it goes wen it starts this .. it getting worse and worse. Now I'm not even driving it.. it's almost acting like there is no gas when there is... and the fuel filter has been changed it didn't help a bit.. ugh..

 

Check your fuel pressure regulator if you have a fuel injected motor.

 

sounds like air leak. don't run engine when it has problems except if to diagnose you might damage it or gum it up or get carbon build-up in cyl area
